Demystifying blockchain: A critical analysis of challenges,applications and opportunities     

《International Journal of Information Management》2020

The blockchain is considered to be the potential driver of the digital economy. The Blockchain technology outweighs the challenges associated with the traditional transaction business governed and regulated by the third trusted party. There is a growth in the interest among the researchers, the industry, and the academia to study and leverage the potential of Blockchain. Blockchain provides a decentralized and distributed public ledger for all the participating parties. Though it seems that blockchain is a viable choice and solution for all the centralized governed and regulated transactions (in digital online space), it has potential challenges that need to be resolved; opportunities to be explored, and applications to be studied. This paper utilizes a systematic literature review to study several research endeavors made in the domain of blockchain. To further research on blockchain adoption, the paper theoretically constructs an integrated framework of the blockchain innovation adoption process in an organization considering organizational and user acceptance perspectives. This would facilitate its widespread adoption, thereby achieving sustained leadership solutions. The paper offers 23 propositions to information systems (IS)/information management (IM) scholars with respect to innovation characteristics, organizational characteristics, environmental characteristics, and user acceptance characteristics. Further, the paper explores several areas of future research and directions that can provide deep insights for overcoming challenges and for the adoption of blockchain technology.  相似文献   

Comparison of crowdsourcing platforms from social-psychological and motivational perspectives     

《International Journal of Information Management》2020

The increasing need to compete in innovation and the prevalence of IT in social and economic interactions have led to greater globalization in innovation sourcing, particularly through online crowdsourcing platforms. Crowdsourcing platform participation, a phenomenon inadequately covered, is an instance of providing an innovative solution or idea intertwined with personal and social factors that interact to result in a behavior. A better understanding of the impact of social factors and participants’ hedonic, utilitarian, and social motivations can guide the design and management of these crowdsourcing platforms to foster sustained engagement. This study considered the competitive and social nature of these platforms and analyzed participation intentions from a novel standpoint—a combination of motivational and socio-cognitive perspectives and their relationships within two different types of crowdsourcing platforms: Atizo’s third-party-hosted community and Nokia’s brand-hosted IdeasProject community. A comparison of these two types of crowdsourcing platforms for the same activity of ideation at an individual level revealed differences in behavior determinants based on the platform host type, domain specificity, and mechanisms supporting different motives and social factors.  相似文献

黄土丘陵沟壑区乡村生态产业化机理及其典型模式   总被引：1，自引：0，他引：1

生态产业化是新时代推进生态建设与产业发展良性循环、促进乡村地域系统可持续发展的重要途径。黄土丘陵沟壑区位于黄河中游地区,作为黄土高原典型地貌单元,其乡村生态环境脆弱、人地矛盾突出,退耕还林（草）工程后生态功能显著改善,但农业基础薄弱、水土约束增强、生产效益偏低等问题依旧突出,亟需推进生态产业化提升乡村生产和生活功能。本文从生态资源价值增殖角度,探讨了黄土丘陵沟壑区乡村生态产业化的内在机理,并结合延安市治沟造地工程后的典型实践,提出了适合该区域发展的产业化模式及其可持续途径。结果表明：①乡村生态产业化应遵循乡村地域系统演化规律、耦合机理以及价值转化原则,依托地理工程技术加快生态资源培育,建立生态产权管理制度实现生态资源资产化,通过资产集中流转、经营主体培育、产业要素融合等推进生态资产资本化,完善生态市场交易机制保障生态产品与服务市场化;②延安市部分乡村依托治沟造地工程实现了生态资源培育,探索了“资源变资产、资产变资本、资本变资金”的路径,已初步形成了高效种养、休闲农业和多元综合等生态产业化模式;③未来应注重地理工程成效管护、健全产权管理制度、发挥能人带动作用、吸纳社会力量参与以及构建动态评价机制,补齐产业化过程中的短板,推进乡村生态、生产、生活的有机融合,实现乡村产业兴旺、生态宜居和生活富裕的振兴目标。  相似文献

European Journal of Special Needs Education Vol. 18, No. 3, October 2003 erratum     

María Cristina Cardona Moltó 《欧洲特需教育杂志》2013,28(1):115-117

The current paper reports on the outcome of an ongoing action research project at a school for higher-functioning students with Autism Spectrum Disorder (ASD) in Sweden. The overall aim of the study was to develop and evaluate a questionnaire that captures social and individual aspects of classroom learning suitable for use with students with ASD. Interview data is presented on the perceived utility of the questionnaire for understanding and planning classroom instruction for the children with ASD through the eyes of the students’ teachers and their parents, as assessed during an Individual Education Plan meeting. Further, teacher ratings obtained by means of the instrument were found to differentiate a group of students with ASD (n = 10) from a group of typically developing children matched with regard to grade year, word reading ability and receptive vocabulary (n = 10). Implications and future directions are discussed, as are limitations of this pilot study.  相似文献   

New Vision and Challenges in Inquiry-Based Curriculum Change in Singapore     

Mijung Kim  Frederick Toralballa Talaue 《International Journal of Science Education》2013,35(2):289-311

A new primary science syllabus with strong inquiry focus has been implemented in Singapore since 2008. In this study, we attempted to understand how teachers experience the emphasis of inquiry-based curriculum under the current educational conditions that is routined and highly teacher fronted. We invited 50 pre-service and 41 in-service teachers to participate in survey questionnaires and narratives, reflective writings, and group discussions related to science inquiry which formed our data corpus. Data analysis in the form of thematic coding was carried out using NVivo8, with over 80% inter-rater coding agreement level. Three key aspects of teachers’ perceptions of science inquiry were revealed: (1) teachers’ responsibilities as facilitators, (2) privileging content knowledge rather than process skills, and (3) pressure of assessment systems in current educational contexts. These understandings bring out conflicts of inquiry teaching between teacher- and student-centredness, content and process, and curriculum and assessment. Based on these teachers’ perceptions and dilemmas of inquiry science teaching, the visions and challenges of inquiry science curriculum change against assessment requirements are discussed.  相似文献
